Message:

from a html source, using dom and xpath how would I return an array containing all the div class names? I use the following which returns all the div class names that contain "XX", but don't know the query to use for $targets to return all. I know this should be simple but I can't find one that works.

   $doc = new DOMDocument();

   $doc->loadHTML($data);

   $xpath = new DOMXpath($doc);

   $targets = $xpath->query(".//div[contains(@class, 'XX')]");

   $classNames_array = array();

   foreach ($targets as $target) {

   $classNames_array[] = $target->textContent;

   }

   print_r(array_values($classNames_array));

Thanks.

My Answer:
$html = '';
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$divs = $xpath->query('//div/@class');
$classNames = array();
foreach ($divs as $div) {
$classNames[] = $div->nodeValue;
}
print_r($classNames);
?>
This code will output:
Array
(
[0] => class1
[1] => class2
[2] => class3
)
